Final-state interactions and superscaling in the semi-relativistic approach to quasielastic electron and neutrino scattering
(The American Physical Society, 2007)
The semi-relativistic approach to electron and neutrino quasielastic scattering from nuclei is extended to include final-state interactions. Starting with the usual nonrelativistic continuum shell model, the problem is ...

Mediterranean temporary ponds as amphibian breeding habitats: The importance of preserving pond networks
(Springer Nature, 2009)
We describe the spatial and temporal variation in the main characteristics of amphibian breeding habitats in Doñana National Park (south of Spain), during two hydrologic cycles with different rainfall amounts and timing ...

HPT and cocyclic operations
(International Press, 2005)
We reinterpret the classical theory of cocyclic operations in terms of permutations and homotopy equivalences of explicit chains. The essential tools we use are Homological Perturbation Theory and Eilenberg–Zilber ...

Analytical theory of extraordinary transmission through metallic diffraction screens perforated by small holes
(Optical Society of America, 2009)
In this letter, the problem of extraordinary (ET) transmission of electromagnetic waves through opaque screens perforated with subwave- length holes is addressed from an analytical point of view. Our purpose was to find a ...

Relative prices and inflation: new evidence from different inflationary contexts
(Taylor & Francis, 2006)
This paper analyses the relationship between inflation and relative price variability, in the direction of the latter, in two countries with very different inflationary experiences: Argentina and Spain. To address this ...

Transfer of Cd, Pb, Ra and U from Phosphogypsum Amended Soils to Tomato Plants
(Springer, 2009)
About 170 million tons of phosphogypsum (PG) are annually generated worldwide as a by-product of phosphoric acid factories. Agricultural uses of PG could become the main sink for this waste, which usually contains significant ...

The cumulative effect of three decades of phosphogypsum amendments in reclaimed marsh soils from SW Spain: 226Ra, 238U and Cd contents in soils and tomato fruit
(Elsevier, 2008)
Phosphogypsum (PG), a by-product of the phosphate fertiliser industries, has been applied as soil amendment to reduce Na saturation in soils, as in the reclaimed marsh area from SW Spain, where available PG has a typical ...

Biprobabilistic values for bicooperative games
(Elsevier, 2008-07)
The present paper introduces bicooperative games and develops some general values on the vector space of these games. First, we define biprobabilistic values for bicooperative games and observe in detail the axioms that ...

Biomonitoring of heavy metals in the coastal waters of two industrialised bays in southern Spain using the barnacle Balanus amphitrite
(Taylor and Francis online, 2008)
This paper evaluates the bioavailability of As, Cd, Cu, Mn, Hg, Ni and Zn in the coastal waters of the two most important bays in southern Spain (Cádiz and Algeciras). Concentrations of these metals were measured in the ...
